longValue

parseLong

Parses the string argument as a signed decimal long.
The characters in the string must all be decimal digits, except
that the first character may be an ASCII minus sign
'-' (\u002d') to indicate a negative
value. The resulting long value is returned, exactly as if the
argument and the radix 10 were given as arguments to the
parseLong(String, int) method that takes two arguments.

Note that neither L nor l is permitted to appear
at the end of the string as a type indicator, as would be permitted
in Java programming language source code.

parseLong

Parses the string argument as a signed long in the
radix specified by the second argument. The characters in the
string must all be digits of the specified radix (as determined by
whether Character.digit returns a
nonnegative value), except that the first character may be an
ASCII minus sign '-' ('\u002d' to indicate
a negative value. The resulting long value is returned.

Note that neither L nor l is permitted to appear at
the end of the string as a type indicator, as would be permitted in
Java programming language source code - except that either L
or l may appear as a digit for a radix greater than 22.

An exception of type NumberFormatException is thrown if any of
the following situations occurs:

toString

Returns a String object representing this Long's value.
The long integer value represented by this Long object is converted
to signed decimal representation and returned as a string, exactly
as if the long value were given as an argument to the
toString(long) method that takes one argument.

toString

Returns a new String object representing the specified integer.
The argument is converted to signed decimal representation and
returned as a string, exactly as if the argument and the radix
10 were given as arguments to the
toString(long, int) method that takes two arguments.

toString

Creates a string representation of the first argument in the
radix specified by the second argument.

If the radix is smaller than Character.MIN_RADIX or
larger than Character.MAX_RADIX, then the radix
10 is used instead.

If the first argument is negative, the first element of the
result is the ASCII minus sign '-'
('\u002d'. If the first argument is not negative,
no sign character appears in the result.

The remaining characters of the result represent the magnitude of
the first argument. If the magnitude is zero, it is represented by
a single zero character '0'
('\u0030'); otherwise, the first character of the
representation of the magnitude will not be the zero character.
The following ASCII characters are used as digits:

0123456789abcdefghijklmnopqrstuvwxyz

These are '\u0030' through '\u0039'
and '\u0061' through '\u007a'. If the
radix is N, then the first N of these
characters are used as radix-N digits in the order
shown. Thus, the digits for hexadecimal (radix 16) are
0123456789abcdef.
